J. KLUG BLOW BALL May 24, 1938.

Filed March 5, 1957 INVENTOR JOHANNA KLUG "It 7 1 I ATTORNEY Patented May 24, 1938 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to new and useful improvements in a blow ball.

The invention has for an object the construction of a blow ball which is characterized by a cup shaped body with'an axial air passage area at its center and a plurality of intermediately inclined air passage areas around its periphery roughly forming an imaginary come within the compass of which a light ball may be blown around.

Still further the invention proposes the provision of means for connecting the air passage areas to facilitate supplying air simultaneously to cause said ball to float within the imaginary cone.

Still further the invention contemplates making use of a mouth stem by which to supply the air to said passages.

Still further the invention contemplates adapting the blow ball device to a display stand and then providing a blower or other supply of air for its operation.

Still further the invention contemplates an arrangement by which the inclination of the air passage on the periphery of the cup shaped body may be varied to vary the size of the imaginary cone and thus the compass through which the ball may be moved.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:--

Fig. 1 is a perspective view of a blow ball device constructed according to this invention.

Fig. 2 is a bottom view of Fig. 1.

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2.

Fig. 4 is a plan view of a blow ball constructed according to a modification of this invention.

Fig. 5 is a fragmentary enlarged detailed View of a portion of Fig. 4 showing in particular one of the slots and one of the air passage areas.

Fig. 6 is a sectional view taken on the line 6--6 of Fig. 5.

Fig. 7 is a sectional view of a display stand with a blow ball device mounted thereon.

The blow ball device, according to this invention, comprises a cup-shaped body I having an axial air passage area II at its center and a plurality of inwardly inclining air passage areas l2 around its periphery roughly forming an imaginary cone l3, indicated by dot and dash lines. A light ball or other similar light object is rested upon the body II]. A means is provided for connecting the air passage areas II and I2 to facilitate supplying air to them simultaneously to cause said ball to float within said imaginary cone.

The body [0 has a central concave portion ill in which the ball it may be rested. It is at the bottom. of this concave portion that the axial air passages I l are located. The body In is also provided with a flange portion 18 It is in this flange portion that the plurality of inclined air passage areas l2 are located. The means for connecting the air passages includes a mouth stem l5 which may be engaged in ones mouth and through which air may be blown. The inner end of this stem [5 connects with a chamber l6. From this chamber the passages l I extend to the center of the body l0. Also from this chamber 48 there are hollow ridge portions ll connecting the chamber 16 with the passages l2.

When. air is blown through the stem l5 it will discharge from the axial air passage area I! to blow the ball l4 axially and the ball will be confined within the cone l3 by the streams of air which pass through the inwardly inclining air passage areas l2.

In Figs. 4-6 inclusive a modification of the invention. has been disclosed in which an arrangement is provided for changing the inclination of the peripheral air passage areas. According to this form of the invention each air passage consists essentially of a nozzle l2 which has a cylindrical socket portion l2 arranged to pivot so that the nozzle portion I2 moves along a radius of the body 10. An annular member 25! is secured upon the body Ill by screws 2 I. This annular member 20 formsv the top portions of the sockets which hold the cylindrical socket portions l2 Another annular member 22 is mounted on the annular member 20 and is slightly rotative relative thereto. This is accomplished by several screws 23 engaging through slots 24 in the annular member 22 and mounted in the member 20. This annular member 22 is provided with projecting handles 25 by which it may easily be turned. For each nozzle l2 there is an inclined slot 26 in the member 22 through which the nozzle extends. These inclined slots are arranged at angles so that as the annular member 22 is turned relative to the member 2|] the nozzles l2 will be radially pivoted.

Thus when the annular member 22 is turned clockwise, with respect to Fig. l, the nozzles 12' will be pivoted towards the axis of the body It], and when the annular member 22 is moved anticlockwise they will be pivoted away from the axis of the body. The changing the inclinations of the nozzles I2 changes the size of the imaginary cone within which the ball is maintained.

In Fig. 7 another modified form of the invention has been disclosed in which a ball device is mounted in an opening 28 in the top wall 29 of a housing 30. This housing has an interior compartment 3| in which a fan or blower 32 is arranged. This blower 32 is capable of supplying air which will pass through the stem I5 and supply the air to the various air passage areas as previously described. Thus the ball [4 will be automatically blown around within the theoretical cone.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
